Remarkable progress has recently been made in the development and application
of quantum trajectories as a computational tool for solving the time-dependent
Schr¨odinger equation. Analogous methods for stationary bound states are also
being developed. Each year, there have been significant extensions and improvements in the basic methodology, and applications are being made to systems with
increasing complexity and dimensionality. In addition, novel quantum trajectory
methods are being developed for a broad range of dynamical problems, such as
mixed quantum–classical dynamics, density matrix evolution in dissipative systems, and electronic nonadiabatic dynamics.
The purpose of this book is to present recent developments and applications of
quantumtrajectorymethods in the broader context of the hydrodynamical formulation of quantum dynamics.
